A saturated calomel electrode (SCE) was used as reference electrode, and a platinum wire (1 cm in diameter) as counter electrode. A rectangle thermoplastic shim (0.9 mm in thickness) was used to create the crevice, with a Lucite as a coating membrane. The plastic shim was adjustable to control the crevice width. A hole of 3.5 cm 1 cm was opened to simulate a holiday. Three ports were then drilled at an interval of 5 cm from the holiday along the Lucite block to position the microelectrodes for measurements of local potential, solution pH and oxygen concentration, respectively. |
